Sure, a mistake made by "smalltalk user" can lead to problems, which:
a) easy to reproduce , since scripts is provided
b) easy to fix , because of a)
c) easy to distribute fix, by fixing a script

and compare this to a mistake, done by a "master" who did something
which only he can understand, and which only he could fix, and as its
often happens, have no time/will/money to spend fixing the problem he
once introduced.
